Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620842, here are decompositions:

23 + 33620819 = 33620842
29 + 33620813 = 33620842
53 + 33620789 = 33620842
251 + 33620591 = 33620842
263 + 33620579 = 33620842
383 + 33620459 = 33620842
461 + 33620381 = 33620842
491 + 33620351 = 33620842

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.1.3.106.

Address: 2.1.3.106
Class: public
IPv4-mapped IPv6: ::ffff:2.1.3.106

Public, routable address (assignable to a host on the internet).
